                            PROXY STATEMENT FOR THE
                  2001 ANNUAL GENERAL MEETING OF SHAREHOLDERS
                            ------------------------

    The letter from the Chairman of the Company (the "Chairman's Letter"), the
reasons for the resolutions and the Notice of Annual General Meeting, each
prepared in accordance with English practice, accompany this proxy statement and
are incorporated by reference herein.

                     SOLICITATION AND REVOCATION OF PROXIES

    The Board of Directors of Shire Pharmaceuticals Group plc (the "Company") is
soliciting the accompanying proxy for use at the Annual General Meeting of
Shareholders (the "Meeting") to be held on 5 June 2001 at the offices of West LB
Panmure Limited at New Broad Street House, 35 New Broad Street, London EC2M 1SQ,
England. If a proxy is received before the Meeting, as indicated below, the
shares represented by it will, on a poll, be voted unless the proxy is revoked
by written notice prior to the Meeting. If matters other than those set forth in
the accompanying Notice of Annual General Meeting are presented at the Meeting
for action, the proxy holders will vote the proxies as they think fit. The
approximate date on which a definitive proxy statement and the accompanying
proxy will first be mailed to shareholders is 27 April 2001.

              SHAREHOLDERS ENTITLED TO VOTE AND SHARES OUTSTANDING

    Only shareholders of record at the close of business on 3 June 2001 will be
entitled to vote at the Meeting. As of 24 April 2001 there were 258,031,902
Ordinary Shares of the Company, nominal value 5p (the "Ordinary Shares"),
outstanding and entitled to vote at the Annual General Meeting. Of these shares
26,384,010 were held in the name of Guaranty Nominees Limited, as nominee for
Morgan Guaranty Trust Company of New York, as depositary (the "Depositary"),
which issues Company-sponsored American Depositary Receipts ("ADRs") evidencing
American Depositary Shares which, in turn, each represent three Ordinary Shares.

    Each registered holder of Ordinary Shares present in person at the Meeting
is entitled to one vote on a show of hands, and every holder present in person
or by proxy shall, upon a poll, have one vote for each Ordinary Share held by
such holder. In the event that the proxy card is executed but does not indicate
by marking a vote "FOR", "AGAINST" or "ABSTAIN," the proxy may vote or abstain
at his discretion. An abstention and a "broker non-vote" are counted only for
purposes of determining the presence of a quorum at the Meeting. "Broker
non-votes" are votes that brokers holding shares of record for their customers
(I.E., in "street name") are not permitted to cast under applicable regulations
because the brokers have not received clear voting instructions from their
customers.

    A member entitled to attend and vote may appoint one or more proxies to
attend and, on a poll, vote instead of him. A proxy need not also be a member.
The appointment of a proxy will not preclude a member of the Company from
attending and voting in person at the meeting if he or she so desires.

    Proxy voting cards from holders of Ordinary Shares must be received by the
Registrar not later than 11:00 A.M. on 3 June 2001 (or not less than forty-eight
hours before any adjournment of the Meeting).

    A Deposit Agreement exists between Morgan Guaranty Trust Company and the
holders of ADRs pursuant to which holders of ADRs are entitled to instruct the
Depositary as to the exercise of voting rights pertaining to the Ordinary Shares
so represented. The Depositary has agreed it will endeavor, insofar as
practicable, to vote (in person or by delivery to the Company of a proxy) the
Ordinary Shares registered in its name in accordance with the instructions of
the ADR holders. Instructions from

the ADR holders should be sent to the Depositary so that the instructions are
received by no later than 3:00 P.M. New York City time on 30 May 2001.

    Any holder of ADRs giving instructions to the Depositary has the power to
revoke the instructions by delivery of notice to the Depositary at Morgan
Guaranty Trust Company of New York, Depositary, P.O. Box 9383, Boston, MA
02205-9958 at any time so that the Depositary receives, by no later than
3:00 P.M. New York City time on 30 May 2001, duly executed instructions bearing
a later date or time than the date or time of the instructions being revoked.

    The cost of soliciting proxies in the form enclosed will be borne by the
Company. In addition to the solicitation by mail, proxies may be solicited
personally, or by telephone, or by employees of the Company. The Company may
reimburse brokers, custodians, nominees, the Depositary and other recordholders
of the Company's Ordinary Shares or ADRs for their expenses in sending proxy
material to the beneficial owners of such Ordinary Shares or ADRs.

    Shareholders may obtain copies of the Company's Annual Report on Form 10-K
as filed with the Securities and Exchange Commission without charge by writing
to the Company at Hampshire International Business Park, Chineham, Basingstoke,
Hampshire RG24 8EP England, attention Company Secretary.

    Resolutions 1 to 8 represent the business of the Company which is commonly
transacted at annual general meetings. Resolution 9 relates to the Shire
Pharmaceuticals Group plc 2000 Executive Share Option Scheme. Resolutions 1 to 9
will all be proposed as ordinary resolutions. Ordinary resolutions require
approval by a 50% plus vote of shareholders.

           SHAREHOLDER PROPOSALS FOR THE 2002 ANNUAL GENERAL MEETING

    The Company will, in future proxy statements, include shareholder proposals
complying with the applicable rules of the U.S. Securities and Exchange
Commission and any applicable U.S. state laws. In order for a proposal by a
shareholder to be included in the proxy statement relating to the Annual General
Meeting of shareholders to be held in 2002, that proposal must be received in
writing by the Secretary of the Company at the Company's principal executive
office no later than 2 January 2002. This requirement is without prejudice to
shareholders' rights under the U.K. Companies Act 1985 to propose resolutions
that may properly be considered at that meeting.

                  RESOLUTION 1. DIRECTORS' REPORT AND ACCOUNTS

    Under English law, each company is required to present at a shareholders'
meeting copies of the company's audited annual financial statements, a report of
the directors and the report of the auditors on those financial statements.
Shareholders are being asked to adopt the financial statements. Adoption merely
means that the shareholders acknowledge that the financial statements have been
distributed and presented at the meeting; it does not in anyway waive or limit
any rights shareholders may have with respect to the financial statements.

    THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ADOPTION OF THE
FINANCIAL STATEMENTS.

                    RESOLUTION 2. REAPPOINTMENT OF AUDITORS

    The Board of Directors recommends that its appointment of the firm of Arthur
Andersen as the auditors of the Company for the fiscal year ended December 31,
2001, be approved and that the Board be given the authority to determine their
remuneration. Arthur Andersen has served as the Company's independent auditors
since January 1994. The Company is advised that no member of Arthur Andersen has
any direct financial interest or material indirect financial interest in the
Company or any of its subsidiaries or, during the past three years, has had any
connection with the Company or any of its

                                       2

subsidiaries in the capacity of promoter, underwriter, voting trustee, director,
officer or employee. A representative of such firm is expected to be present at
the meeting, will be available to answer questions and will be afforded an
opportunity to make a statement if he or she so desires.

AUDIT FEES

    The aggregate fees billed for professional services rendered for the audit
of the Company's annual financial statement for the fiscal year ended
December 31, 2000 and for the reviews of the financial statements included in
the Company's Quarterly Reports on Form 10-Q for that fiscal year were $530,000.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

    Arthur Andersen did not render professional services relating to financial
information systems design and implementation for the fiscal year ended
December 31, 2000.

ALL OTHER FEES

    The aggregate fees billed by Arthur Andersen for services rendered to the
Company, other than the services described above under "Audit Fees" for the
fiscal year ended December 31, 2000, were $2,110,000. The vast majority of these
fees relate to corporate and employee related tax matters.

    The Audit Committee considered whether the provision of services described
above under "All Other Fees" is compatible with maintaining Arthur Andersen's
independence.

    THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF THE
APPOINTMENT OF ARTHUR ANDERSEN AS INDEPENDENT AUDITORS OF THE COMPANY FOR THE
YEAR 2001.

           RESOLUTIONS 3 TO 8. ELECTION AND RE-ELECTION OF DIRECTORS

    The Company currently has ten Directors.

(1) For purposes of this table, a person or a group of persons is deemed to have
    "beneficial ownership" as of a given date of any shares which that person
    has the right to acquire within 60 days after that date. For purposes of
    computing the percentage of outstanding shares held by each person or a
    group of persons named above on a given date, any shares which that person
    or persons has the right to acquire within 60 days after that date are
    deemed to be outstanding, but are not deemed to be outstanding for the
    purpose of computing the percentage ownership of any other person.

(2) Based on the 101,607,536 outstanding shares of BioChem as of 24 April 2001.
    Assumes that all BioChem shares are exchanged for new ordinary shares and,
    based on the closing price of the Company's ADSs of $46.51 (being the
    closing price of an ADS on 17 April 2001), that such shares are exchanged at
    a rate of 2.3517 new ordinary shares for each BioChem Share. Also assumes
    that no BioChem options are exercised prior to or in connection with the
    merger.

(3) Based solely on information provided to the Company by Putnam Investment
    Management, LLC & The Putnam Advisory Company, Inc. on 3 January 2001.

(4) Dr. Cavanaugh is the President of HealthCare Ventures LLC, which is the
    management company for a number of limited partnerships which have interests
    in 8,690,090 Ordinary Shares. Dr. Cavanaugh is also a general partner in
    these partnerships. 8,690,090 of the shares in which Dr. Cavanaugh is
    expressed to be interested represent shares held by those partnerships and
    not by Dr. Cavanaugh personally. The remaining 116,278 shares are held by
    Dr. Cavanaugh as beneficial owner.

(5) Includes 964,774 ordinary shares issuable upon exercise of options.

(6) All of Dr. Totten's shares are issuable upon exercise of options.

(7) Dr. Canavan is interested in 11,000 BioChem shares. Based on the closing
    price of the Company's ADSs of $46.51 (being the closing price of an ADS on
    17 April 2001), Dr. Canavan's shares would be exchanged at a rate of 2.3517
    new ordinary shares for each existing BioChem share.

(8) Includes 121,210 ordinary shares issuable upon exercise of options.

(9) Includes 78,200 ordinary shares issuable upon exercise of options.

(10) Dr. Bellini and Mssrs. Grant and Veilleux have been appointed as Directors
    of the Company conditional on completion of the Company's merger with
    BioChem. The figures for their interests assume that, based on the closing
    price of the Company's ADSs of $46.51 (being the closing price of an ADS on
    17 April 2001) and assuming each of them elects for new ordinary shares,
    their shares would be exchanged at a rate of 2.3517 new ordinary shares for
    each existing BioChem Pharma share they hold. The figure for their interests
    include ordinary shares (7,055,100 for Dr. Bellini, 240,578 for Mr. Grant
    and 34,099 for Mr. Veilleux) that would be issuable upon exercise of Shire
    options received in exchange for their BioChem Pharma options based on the
    2.3517 exchange ratio.

(11) This number does not include Dr. Horovitz and Mssrs. Smith and Spitznagel.

               BOARD OF DIRECTORS' MEETINGS, COMMITTEES AND FEES

    The Board of Directors held 10 meetings during 2000. Each incumbent director
attended at least 75% of the aggregate of the total number of meetings of the
Board of Directors and the total number of meetings held by all committees of
the Board of Directors on which the Director served during 2000 (including in
the case of each director for purposes of this calculation only such committee
and Board meetings as occurred after such Director commenced service on the
Board of Directors).

    The Board of Directors has a standing Remuneration Committee, a standing
Audit Committee and a standing Nomination Committee. The membership of these
committees is determined from time to time by the Board.

    The Remuneration Committee, which in 2000 consisted of Dr. Price as
Chairman, Drs. Cavanaugh and Canavan and Mr. Joseph Smith held 4 meetings during
2000. The Remuneration Committee meets regularly and acts within agreed terms of
reference. The Remuneration Committee reviews and authorizes salaries, bonuses
and other matters relating to compensation of the executive officers, including
the granting of options.

    The Audit Committee, which consists of Dr. Canavan, as Chairman, Drs.
Cavanaugh and Price and Mr. Nordmann, held 4 meetings during 2000. In addition,
it has been our practice to provide detailed financial information at each
meeting of the Board of Directors. The principal functions of the Audit
Committee are to review the scope of the annual audit and the annual audit
report of the independent auditors, recommend the firm of independent auditors
to perform such audits, consider non-audit

                                       7

functions proposed to be performed by the independent auditors, review the
functions performed by the internal audit staff, ascertain whether the
recommendations of auditors are satisfactorily implemented and recommend such
special studies or actions which the Committee deems desirable. A copy of the
Audit Committee Terms of Reference is attached hereto as Appendix A.

    The Board has delegated responsibility to a Nomination Committee made up of
two non-executive Directors and one executive director. The Nomination Committee
consists of Dr. Cavanaugh as Chairman, Joseph Smith and Rolf Stahel. The
Nomination Committee intends to adopt formal and transparent procedures for such
appointments during the course of the year. The Nomination Committee will
consider suggestions regarding candidates for election to the Board submitted by
shareholders in writing to the Company Secretary. With regard to the Annual
General Meeting in 2002, any such suggestion must be received by the Company
Secretary no later than the date by which shareholder proposals for such Annual
General Meeting must be received as described above under the heading
"Stockholder proposals for the 2002 Annual General Meeting."

    Our non-executive Directors receive L20,000 (approximately $30,000) on an
annual basis for their services save for Dr. Cavanaugh, who, as non-executive
Chairman, received remuneration of L35,000 (approximately $53,000) for 2000. We
reimburse non-executive Directors for out-of-pocket travel expenditures relating
to their service on the Board.

      COMPLIANCE WITH SECTION 16(A) OF THE SECURITIES EXCHANGE ACT OF 1934

    Section 16(a) of the Securities Exchange Act of 1934 requires our executive
officers and Directors and persons who own more than 10% of a registered class
of our equity securities to file initial reports of ownership and changes in
ownership with the SEC and to furnish copies of these reports to the Company. To
the Company's knowledge, based solely on a review of the copies of such reports
furnished to us and representations that no other reports were required, the
Company believes that all persons subject to the reporting requirements of
Section 16(a) filed the required reports on a timely basis during the year ended
December 31, 2000.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    In April 1999 Roberts Pharmaceutical Corporation made a loan in the sum of
$283,000 to Mr. Spitznagel. The loan was unsecured and bore interest at the rate
of 4.15%, per annum. 10% of the principal outstanding plus accrued interest was
repayable on each of the first four anniversaries of the loan and the balance of
principal plus accrued interest is repayable on the fifth anniversary of the
loan. Mr. Spitznagel repaid the full outstanding balance of the loan on
March 29, 2000.

    Mr. Spitznagel entered into a consultancy agreement with the Company in
December 1999, which provided that:

     i. if he has good reason, as defined in his service agreement with Roberts,
        to terminate his employment with Roberts under his service agreement,
        the Company will cause Roberts to provide him with the payments and
        benefits he is entitled to upon a "good reason' termination;

     ii. Mr. Spitznagel would provide consulting services to the Company for at
         least 42 months following the merger with Roberts, unless
         Mr. Spitznagel terminates the consultancy agreement prior to the end of
         the 42nd month; and

    iii. the Company would pay Mr. Spitznagel at the rate of $400,000 per annum
         for his consulting services, $150,000 per annum as an office holder,
         $250,000 per annum to comply with certain restrictive covenants
         contained therein and $150,000 per annum to be used for tax, financial
         and estate planning advice, life insurance and health insurance.

(1) The potential realizable value uses the hypothetical rates specified by the
    SEC and is not intended to forecast future appreciation, if any, of the
    Company's stock price. The Company did not use an alternative formula for
    this valuation as the Company is not aware of any formula which will
    determine with reasonable accuracy a present value based on future unknown
    or volatile factors. In fact, the Company disavows the ability of this or
    any other valuation model to predict or estimate the Company's future stock
    price or to place a reasonably accurate present value on the stock options
    because all models depend on assumptions about the stock's future price
    movement, which is unknown. The value indicated is a net amount, as the
    aggregate exercise price, translated at the rate of exchange at
    December 31, 2000, has been deducted from the final appreciated value.

(2) The exercise price was L10.275 per share and has been translated at the rate
    of exchange at the date of grant of $1.579: L1.00.

(3) The exercise price was L12.80 per share and has been translated at the rate
    of exchange at the date of grant of $1.494: L1.00.

         REPORT OF THE REMUNERATION COMMITTEE ON EXECUTIVE COMPENSATION

REMUNERATION POLICY

    The Remuneration Committee's policy on the remuneration of executive
officers is directed at the retention and motivation of executive officers by
ensuring that their remuneration is competitive with companies within the sector
of emerging pharmaceutical companies, taking into account the interests of the
shareholders.

    In developing remuneration policy and fixing remuneration, consideration is
given to the salary data of Directors of comparable companies of a similar size
in industry generally and, more specifically, in the emerging pharmaceuticals
sector. The Chief Executive also advises the Remuneration Committee on other
executive remuneration and on individual performance. External agencies are also
used to advise on levels of remuneration as appropriate. No Director is involved
in determining his own remuneration. The procedures and criteria for determining
remuneration policy are regularly reviewed by the Remuneration Committee.

ANNUAL BONUSES

    The annual bonuses payable to executive officers are established on the
basis of objectives for the Company and personal objectives. They include
measurable and quantitative criteria related to financial performance. For the
year ended December 31, 2000, these included revenue and earnings targets. The
maximum annual bonus for each executive officer for the year ended December 31,
2000, was 55% of salary in respect of Mr. Stahel, 50% of salary in respect of
Mr. Russell and 50% of salary in respect of Dr. Totten.

SHARE OPTIONS

    Share options are granted to executive officers as an incentive. The grant
of options is wholly discretionary. In granting share options, the Remuneration
Committee takes into account the advice and recommendations of the Chief
Executive and individual salary levels and positions within the Company.

                                       11

RETIREMENT BENEFITS

    The Company contributes 10% of salary to the personal pension of the
executive officers.

LONG-TERM INCENTIVE PLAN

    The Long-Term Incentive Plan was adopted at the general meeting on June 30,
1998. Under this plan, the Company may at any time, with the approval of the
Remuneration Committee, grant, or request that trustees grant, an award to any
full-time employee of any member of the Company.

    An award may be made to any full-time employee (including a Director who is
also such an employee) of the Company on the terms set out in the plan and upon
such other terms as the Board (or a committee appointed by the Board) may
specify, provided that no award may be granted to an employee who is within two
years of his or her contractual retirement age.

COMPENSATION OF THE CHIEF EXECUTIVE

    The Remuneration Committee's policy on remuneration applies in all respects
to the Chief Executive, Mr. Stahel. Mr. Stahel's base salary of $575,000 for
2000 was based on the Company's need to retain and motivate its executive
directors. In developing remuneration policy and fixing remuneration,
consideration is given to salary data of directors of comparable companies of a
similar size in industry generally and, more specifically in the emerging
Pharmaceuticals Sector. Mr. Stahel was awarded a $316,000 bonus for the year
ended December 31, 2000 in connection with his individual performance and the
performance of the Company as a whole.

TO THE HOLDERS OF ORDINARY SHARES AND, FOR INFORMATION ONLY, TO PARTICIPANTS IN
THE SHIRE EMPLOYEE SHARE SCHEMES.

Dear Shareholder

NOTICE OF ANNUAL GENERAL MEETING
You will find the notice of the Annual General Meeting (the "AGM"), to be held
on 5 June 2001, with this letter together with an explanation of the resolutions
to be proposed at the AGM and a form of proxy. Shire Pharmaceuticals Group plc
(the "Company") is subject to additional US Securities and Exchange Commission
("SEC") rules which have meant that the Company is obliged to file a proxy
statement with the SEC. A copy of the statement is also enclosed with this
letter.

In addition to the business which is conducted at the AGM every year, for
example, the approval of accounts and the appointment of directors, this year
there is further special business which is detailed in the attached notice of
AGM.

The Company proposes to change the manner in which its existing equity incentive
arrangements can operate; in particular the Company is seeking your approval to
change the way in which it can operate the Shire Pharmaceuticals Group plc 2000
Executive Share Option Scheme (the "Executive Scheme") in respect of future
grants. The Company also proposes to amend the performance conditions applying
to the Shire Pharmaceuticals Group plc Long Term Incentive Plan (the "Long Term
Incentive Plan") in respect of future awards and is taking this opportunity to
advise you of the changes.

OVERVIEW
The Company introduced the Executive Scheme and the Long Term Incentive Plan in
order to link participants' remuneration to the Company's performance and
remains committed to maintaining a culture of employee share ownership as an
essential component of its global reward strategy. Since the introduction of
these plans, the size of the Company and the environment in which it operates
have continued to change substantially. In particular, the following
developments have led the Remuneration Committee to review the Company's long
term incentive arrangements and the performance conditions attached to the
Executive Scheme and the Long Term Incentive Plan:

o the North American focus of the business has increased further so that in the
financial year ended 31 December 2000 roughly 63% of our employees were based in
North America and 83% of our revenues were derived from North American markets;

o     the globalisation and consolidation of the pharmaceuticals sector;

o     the increasingly competitive and global market for talented people; and

o     the Company's recent significant growth (leading to its inclusion in the
      FTSE 100 index).








The Company believes that it will be difficult to compete for the talented
people it needs in order to continue delivering increased shareholder value
unless its long term incentive arrangements reflect practice in the markets in
which it operates.

The Company therefore considers that the manner in which performance conditions
are imposed on options granted under the Executive Scheme and the performance
conditions currently applied to awards made under the Long Term Incentive Plan
no longer meet the needs of the business. The proposals outlined below address
these issues and will enable the Company to tailor appropriate
performance-related long term remuneration for its employees. As a part of this
review, the Remuneration Committee has taken specialist advice from independent
consultants.

EXECUTIVE SCHEME
In the international markets in which the Company operates, share options
continue to be the most widely understood and operated form of long term
incentive arrangements. Share options are also an integral part of the Company's
reward strategy throughout the business in line with global market practice. The
Remuneration Committee believes that all options granted under the Executive
Scheme should continue to be subject to stretching performance targets.

The Company operates in a truly international environment and must take account
of North American practice when it seeks to recruit, retain and motivate its
employees and, in particular, its senior executives. Therefore, it is proposed
that, in respect of future grants of options, the Remuneration Committee will be
able to determine whether it is most appropriate to make the grant of options
based on the prior performance of the Company together with the performance of
the individual (in which case no additional conditions will govern their
exercise); or for the exercise of options to be based on the meeting of
performance targets prior to exercise. Under normal circumstances, options will
continue to be exercisable only after the third anniversary of the date of
grant.

Performance conditions to be applied to the grant of such options will be
determined by the Remuneration Committee prior to their grant. In making such a
determination, the Remuneration Committee will have regard to the guidance
issued from time to time by the bodies representing institutional shareholders.
They will seek to identify factors which represent a fair measure of overall
corporate performance such as share price growth, total shareholder return and
earnings per share.

The Remuneration Committee proposes that the performance condition determining
the next grant of such options will be tested over a three year measurement
period prior to their grant. The measure will be consistent with that currently
governing the exercise of options granted under the Executive Scheme: namely,
that growth in the Company's share price over a three year measurement period
must exceed 50% in order for 60% of options to vest and must exceed 75% for full
vesting.

LONG TERM INCENTIVE PLAN
The Long Term Incentive Plan will continue to be used to incentivise executive
directors and the most senior managers within the Company. The Remuneration
Committee will set appropriate performance conditions each time awards are made
under the Long Term Incentive Plan. The extent to which awards under the Long
Term Incentive Plan will vest will continue to be subject to the Company's
performance over a three year performance period.

It is intended that the performance conditions to be applied to the vesting of
the next award granted will be based on the total shareholder return of the
Company relative to the constituents of the FTSE 100 index, which is a more
appropriate comparator group now that the Company has gained entry into this
index. Awards will vest on a sliding scale so that an award will only vest in
full if the Company has delivered superior performance to shareholders and its
total shareholder return over the performance period is such as to rank it in
the top 10% of FTSE 100 companies. If the Company is not ranked in the top 50%
the award will not vest at all.

As is currently the case, if and to the extent that performance conditions are
met over the three year performance period, awards will continue to be deferred
for an additional 12 months.

DILUTION LIMITS
The existing dilution limits in the Executive Scheme and the Long Term Incentive
Plan will remain.

SHAREHOLDING POLICY
The Remuneration Committee is proposing to introduce a shareholding policy which
would require executive directors to build up a meaningful shareholding in the
Company over time. The Remuneration Committee will encourage executive directors
to retain a proportion of shares in the Company following exercise of options
and realisation of awards under the Long Term Incentive Plan. It is proposed
that the target for executive directors be to hold shares with a value
equivalent to their annual salary and that this target be achieved over the next
three to five years.

NOTES
i)    Dr Cavanaugh is the President of HealthCare Ventures LLC, which is the
      management company for a number of limited partnerships which have
      interests in 8,690,090 ordinary shares. Dr Cavanaugh is also a general
      partner in these partnerships which acquired their ordinary shares
      following the acquisition of Pharmavene, Inc. in March 1997. On 14
      September 2000 Healthcare Ventures II, L.P. distributed 2,904,890 of its
      ordinary shares to unrelated third parties, being the beneficial owners of
      such shares, and 649,830 ordinary shares to HealthCare Partners II, L.P.
      On 15 September 2000 HealthCare Partners II, L.P. distributed 533,552
      ordinary shares to unrelated third parties, being the beneficial owners of
      such shares, and 116,278 ordinary shares to Dr Cavanaugh personally as
      beneficial owner.

ii)   On 10 March 2000 Dr Canavan purchased 1,000 ADSs, the equivalent of 3,000
      ordinary shares, for $65.56 per ADS. Dr Canavan is also interested in
      11,000 BioChem Pharma shares. Based on an Average Shire ADS Price of
      $46.51 (being the closing price of an ADS on 17 April 2001), Dr Canavan's
      shares would be exchanged at a rate of 2.3517 new ordinary shares for each
      existing BioChem Pharma share. Dr Canavan can also expect to receive
      payment of approximately $58,000 in respect of his ownership of BioChem
      Pharma's deferred share units.

iii)  On 8 March 2000 Dr Horovitz exercised 31,280 share options under the
      Roberts Stock Option Plan at $3.68 per ordinary share and on the same day
      exercised a further 31,280 share options at $3.64 per ordinary share. On 9
      March 2000 all of the 62,560 resulting ordinary shares were sold realising
      gross proceeds of (pound)743,213.

iv)   On 9 and 10 March 2000 Mr Nordmann exercised 93,840 share options under
      the Roberts Stock Option Plan at $6.02 per ordinary share. On 9 March 2000
      Mr Nordmann sold 50,000 ordinary shares realising gross proceeds of
      $956,250.

v)    On 17 March 2000 Mr Spitznagel exercised 600,000 share options under the
      Roberts Stock Option Plan at a total exercise price of $2,677,616. On 24
      March 2000 Mr Spitznagel exercised a further 334,809 share options under
      the Roberts Stock Option Plan for a total exercise price of $1,890,013.
      During March 2000 Mr Spitznagel sold 934,809 ordinary shares realising
      gross proceeds of $17,073,856. On 19 April 2000 Mr Spitznagel notified the
      Company of a miscalculation of his shareholding in the Company which the
      Company was informed was 57,624 rather than 75,503 ordinary shares as
      previously notified. On 31 October 2000 Mr Spitznagel exercised 255,490
      share options under the Roberts Stock Option Plan at a total exercise
      price of $528,632 and 177,290 share options under the Roberts Stock Option
      Plan at a total exercise price of $1,067,285.5 and on 31 October 2000 sold
      255,490 ordinary shares realising gross proceeds of $4,400,423. On 19
      December 2000 Mr Spitznagel exercised 100,000 share options under the
      Roberts Stock Option Plan at a total exercise price of $602,000. On 19
      December 2000 Mr Spitznagel sold 100,000 ordinary shares realising gross
      proceeds of $1,425,000.

vi)   Dr Bellini, Mr Grant and Mr Veilleux have been appointed as directors of
      the Company conditional on completion of the Company's merger with BioChem
      Pharma. The figures for their interests assume that, based on an Average
      Shire ADS Price of $46.51 (being the closing price of an ADS on 17 April
      2001) and assuming each of them elects for new ordinary shares, their
      shares would be exchanged at a rate of 2.3517 new ordinary shares for each
      existing BioChem Pharma share they hold, and also assume that all their
      options would be exercised.

Copies of the rules of the Executive Scheme and the Long Term Incentive Plan are
available for inspection from the date hereof during normal business hours on
any week day at the Company's registered office at Hampshire International
Business Park, Chineham, Basingstoke, Hampshire RG24 8EP, and at the offices of
Arthur Andersen, 20 Old Bailey, London EC2M 7AN.

Copies will remain available up to and including the date of the AGM (or any
adjourned meeting) and will also be available for inspection at the offices of
West LB Panmure, 35 New Broad Street, London EC2M 1SQ, for at least 15 minutes
prior to and during the AGM.

RECOMMENDATION
The directors have considered Resolutions 1 to 9 which deal with, inter alia,
the proposals relating to the Executive Scheme to be put to shareholders and
believe they are in the best interests of shareholders as a whole and
accordingly recommend that shareholders vote in favour of them at the AGM as
they intend to do in respect of their aggregate beneficial holdings of 9,087,385
ordinary shares, representing approximately 3.5% of the issued share capital of
the Company.

Yours faithfully

EXPLANATION OF RESOLUTIONS
Resolutions 1 to 8 represent the business of the Company which is commonly
transacted at Annual General Meetings. Resolution 9 relates to the Shire
Pharmaceuticals Group plc 2000 Executive Share Option Scheme (the "Executive
Scheme"). Resolutions 1 to 9 will all be proposed as ordinary resolutions.

RESOLUTION 1: ANNUAL REPORT
This resolution receives the Company's Annual Report and Accounts for the year
ended 31 December 2000.

RESOLUTION 2: REAPPOINTMENT OF AUDITORS
The approval of shareholders is sought for the reappointment of Arthur Andersen
as the Company's auditors for the next financial year and to provide the Board
with authority to determine their remuneration.

RESOLUTIONS 3 TO 8: ELECTION AND RE-ELECTION OF DIRECTORS
The Company currently has ten directors.

The Articles of Association of the Company provide that one-third of the
directors who are subject to retirement by rotation, or if their number is not
three or a multiple of three, then the number nearest to but not exceeding
one-third shall retire at the meeting. The directors to retire by rotation at
the meeting include, so far as necessary to obtain the number required,
first, a director who wishes to retire and not offer himself for
reappointment, and, second, those directors who have been longest in office
since their last appointment or reappointment.

The Articles of Association of the Company also allow the Board of Directors of
the Company to appoint a person who is willing to act as a director. A director
appointed in this way may, however, hold office only until the dissolution of
the next Annual General Meeting after his/her appointment unless he/she is
reappointed during the meeting.

In accordance with the Articles of Association, Mr Angus Russell, Dr Wilson
Totten and Dr Bernard Canavan retire by rotation and offer themselves for
re-election. Dr Francesco Bellini, the Hon James Andrews Grant and Mr GErard
Veilleux, who have been appointed non-executive directors conditional on
completion of the merger with BioChem Pharma, will also offer themselves for
election, assuming that the Company's merger with BioChem Pharma Inc. ("BioChem
Pharma") has been completed by the Annual General Meeting. The biographical
details of these directors are set out below.

RESOLUTION 9
As explained in the Chairman's letter, the Company has undertaken a review of
the performance conditions attaching to its long term equity incentive
arrangements in the light of its growth and the international environment in
which it operates.

As a result of this review the Company is seeking the approval of shareholders
to change the manner in which the Executive Scheme may be operated so that the
Remuneration Committee may impose performance conditions on the grant of options
under the Executive Scheme, in which case there will be no further conditions
governing the exercise of such options.
